Getting used to my 916 but after a recent blast the temp stayed up around 100 while I was trickling through town and it started spluttering but seemed to clear up when it cooled down eventually but made for a few uncomfortable minutes riding! It this totally odd or typical? Cooling system seems clean and moving and air flow is clear. Ta

Try this:

MOTUL MoCool additive
this will drop the temps by 15c

MW Tuning Low Temp Fan Switch: Ducati 748, 916, & 996
will turn on the fan earlier.

Thanks for the advice. Does anyone think my bike is running too hot or is the above normal and tolerable or is something not right?

My bike has a 916 engine with 996 top end and head work. It gets pretty hot in traffic. It sits at about 100 deg once the fan comes on. I think it's normal. It's been up to 110 deg but didn't really bother it too much. The 748 engine I used to have in it never got near 100 degrees.

That's some comforting news thanks! Did you have any running problems at high temps in traffic?

One thing that's often overlooked on Ducatis is that both oil and coolant radiator fin damage occurs from road debris. Without protection, the fins get bent over, air flow through the radiator is reduced, so coolant and oil temperatures rise over time. A first step is to carefully straighten the bent fins.

The Ducati cooling system is designed to keep the engine coolant temperature at 180°F when you're moving at speed on a 90°F day. Temperatures will rise as you slow down for traffic.

Thanks guys. Would the spluttering be the result of higher temp running? All fins etc are clean after a couple of hours of cleaning.

Running hot shouldn't cause spluttering. It does cause a noticeable loss of power, but that's usually due to ambient hot air being sucked in to the air box. If you have spluttering when your engine gets hot, it would depend on where in the rev range, what mods are done to the engine/exhaust/ECU/air filters. Also, does it happen when the tank is full of fuel as well as when it's low on fuel?

When my 998 was getting too hot it had a tendency to stall as I came off the throttle when stopping. I changed to Motocool coolant, swapped on the Speedymoto water pump cover and did a lower temp fan switch. Much better since.

Plenty of fuel and happened when opening-up from low speeds in traffic. Did seem to settle down on cooling but by that time I had reached home as I didn't fancy risking it! Thanks
